Abstract :

Nowadays the portfolio of financial assets play an important role in the creation of new liquidity of the assets that its fund return requires to perform the obligations of debtors over time. But using these financial tools necessary to pay special attention to the issue of risk in financial assets because if there is any risk in assets it will produce greater effects after becoming securities. In the event of a crisis in financial assets, the relevant securities create irreparable damage to its owner’s. The problem stems from the fact that one of the main purposes of portfolio is diversification, then the aim of risk management is selecting the securities with low correlation to reduce portfolio volatility. However, the most important impact of stressful events is that the correlations that existed under normal conditions change and risk managers face a new correlations that will lead to unexpected concentration risk. Also, the banks pay loans to different industries and in varies currencies and they diversify their portfolio in this way. However, in times of stress, all these industries are more likely to default on their debt, and consequently ineffective to provide diversification. The aim of this paper is introducing stress test as one of risk management instruments that it examine the effects of risk assets, especially in critical situations then it has special application in securitization process assessment.
